TURBINE FOR BOILER-CLEANERS.

To all whom it may concern:

Be it known that I, FRANK M. FABER, of Pittsburg, Allegheny county, Pennsylvania,

have invented a new and useful Turbine for Boiler-Cleaners, of which the following is a full, clear, and "exact description, reference bein had to the accom anvin drawin s,

D u b forming part .of this specification, in which Figure 1 is a side elevation of my improved turbine-cleaner with the turbine and case in- Fig. 2 is a front elevation of the case. 1

section. Fig. 3 is a side elevation of the same broken awayto show the-vanes; and Fig. 4 1s a rear end elevation, partly in section.

1 structure of the turbine-case and contained arts, to provide a collecting-chamber for eakage, w 'ch will prevent water being forced .into the journal, and to provide a thrustbearing for the cleaner-shaft.

' In the drawings, 2 is the turbine-case of oylindrical form with ahose-coupling 3 screwed within its rear end.

i is the turbine-wheel proper, having curved passages 5 in its periphery, which are closed at the outer side by the inclosing band or ring 6, with a beveled inner face secured by screws.

passages 9, with an inclosingband 10, secured y-screws 11,-this band having a beveled inner face similar to that on the turbine-wheel.

This stationary feed portion is held 'within the case by radial projections 12, secured to the case 2 by screws 13. The turbine-shaft 14 is provided with a projecting collar 15, 45

resting against the annular flange 16 "of the bushing 17. The bushing 17 is held by in- I wardly-projecting bearings or ring portions 8 of the casing 8. The shaft has the larger threaded lportion 18 screwing within the turbine shel and the smaller threaded portion 19, to which the universal joint 20 is screwed.

Between the turbine-shell and the stationary portion extending within it is provided Specification of Letters Patent.

an annular chamber 21, with outlet-holes 22 into a chamber 23, formed Within the rear portion of the stationary turbine art, and to resist the tendency to draw t 's shaft forwardly and out of the case, caused by the high pressure of the water, I provide a thrustrbearing within this chamber. The part of the shaft within the chamberis threaded, a nut 24 being screwed upon it. Between this nut and the front wall of the chamber are alternate disks 25 of bronze and 26 of steel. The forward steel disk has proj ecting lugs 27, which engage oorres )onding recessesin the front wall of the chamber. These thrust disks loosely surround the threaded shaft and may be tightened or loosened by turning the nut. The nut is held'in adjusted position by the locking-washer 28, having bent projections engaging notchesin the nut and held by lock-nut 29. The rear end of this thrust-bearing chamber is closed in by the screw-cap to prevent access of the water to the bearing and to close the chamber and enable the bearing to run in oil.

The advantages of my invention result from the use of the annular leakage-chamber with its outlet, from the thrust-bearing, which takes up the pull on the shaft, from the inclosed grease-chamber for the bearing and means for-adjustment, and the general arrangement of the case and its parts.

Many variations may be made in the form and arrangement of the head, the case, and the contained parts without departing from mydnvention.

1. In a turbine, a case having a fluidchamber in its rear portion and a stationary turbine part infront of said chamber with fluid-supply passages extending through it in annular form, a turbine-shaft extending rearwardly through-the body of the stationary turbine part and terminating in a central I 5 thrust bearing chamber, a thrust bearing within said chamber and a cap for the chamber arranged to close its rear end; substantially as described.
